MEET CUPSchat Arnold Schumann, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) professor of soil, water and ecosystems sciences, pioneered CUPS research in Florida. His …
By Sarah Strauss One of the keys to good cover crop germination, and thus the potential benefits to soil health, is timing planting with summer rains. As cover crops are planted to improve soil health and are not harvested for profit, you want them to require as little effort on your part as possible. Relying on rain for irrigation can …
By Ramdas Kanissery As the summer season of weed control kicks off in citrus groves, now is the perfect time to make sure your spray rigs are set up for success.
